CHAIR.

` Application filed November This invention relates to chairs, and has special reference to cha-irs for suppertingthe operator and-the work and embodying structure; for maintaining the chair parts in proper relationship. j n

-An object of the invention isv to provide a i work chair comprising a supporting frame, a

seat for the operatorv or worker, in combina.-A tion with a `support for the work movably supported by the frame below the seat and movable to and from positions: to afford access to the work carried thereby. l

Ano-ther object ofv the invention is to provide an improved portable support for an operator and the work, including a support ing frame, a seat and back for the operator on the frame, in combination with a. support for the work mounted inthe frame below the seat and movableto and from positions to afford access to the work, and meansgfor strengthening t-he ,entire structure so that the work support will be operative irrespective vof the strains to which the device is subjected.

Other objects of the invention will appear from the accompanying description, reference being made to the drawing in which Fig. 1 is a front elevation of my improved chair. y

Fig. 2 is a side elevation.

Fig. 3 is a rear elevation.

Fig. et is a cross sectional view through the seat andthe work support.

Fig. 5 is a front to rear sectional View through the seat and work support.

My improved chair comprises a supporting frame including four legs 1, of which the two front legs are rigidly connected by a transverse member 2preferably attached to the front sides of the legs 1 and extending laterally beyond the side edges thereof, so that one end is Hush with the outer surface of the vertically wide part 3 attached to the outer sides of one of the front and one of the rear legs; and the other end is flush with the outer surface of a vertically narrow part l rigidly connecting the front and rear legs at the opposite side of the chair. The two rear legs are connected by a transverse vertically Wide member 5 having its ends in the same planes Vwith the outer surfaces of the members 3 and 1e A relatively narrow transverse strip 6 is attached to and connects the inner sides of the front legs, and a similar transverse strip 7 is attached to and connects the inner sides of the two rear legs. These strips are of equal 11, 1925. serial No. 68,294.

width and are of narrower width members 2 and 5. l

` Metallic corner plates 8 are fastened in the upper corners of the frame thus constructed by the bolts 9 whereby vthe respective,frameI members 2, 3, l and 5 are attached to the'legs 1. These devices in cooperation with the seat back of the chair produce a. structure of th an the sufficient strengthV to resist the strains to which the chair is subjected, whether on levelv or irregular surfaces, so that the chair can be used as well outdoors upon the ground as indoors upon a floor.

The chair may be constructedv as a rocking chairwith rockers 10, or not as desired. l prefer to use rockers of wide vertical width as shown, in which case the rockers are at tached to the lower ends of the legs by bolts 11, and are preferably seated Y in' notches formed at the lower ends of the legs as shown i (Fig. 1). l

The seat ofthe chair asshown is made of a number of transverse slats 12 attached'to the end and side frame members 2, 3, 4 and 5, and preferably extending beyond the front,

. side and rear edges thereof, as will be understood by reference to Figs. 1 and 2.

The backof thev chair comprises an upwardly and rearwardly'inclined back mem- `ber 13,V preferably possessing a degree of re siliency and having its lower end provided with notches 14 softhat the lower end may be fitted closely between the rear legs 1 to utilize the lower end of the back as a. part of the strengthening frame of the chair to re- 'ceive strains to which the legs are subjected when the chair is in'use.

A cross connection 15 is secured between the two rear legs in front of the rear surfaces of the legs, and the lower end of the back 13 which is between the legs is attached to said cross connection by bolts 16. The back bears closely against the rear edge of the rear slat 12 and is secured to the rear frame member 5 by screws or bolts 17 and is thereby held in close contact with the rear edge of the slat 12. The upper portion of the seats between the back 13 and the rear frame member 5 contains a filler 18 forming a further rigid abutment for the back, below the slat 12` To obtain easy portability a handle 19 is attached to the rear side of the back'l by screws 2O passing through the handle, through the back and into the rear slat 12.

The front and rear legs respectively are 2 i Y p The work support comprises a bottom wall 22 mounted for sliding movements upon the" supports 2l, vertical side walls 23 arranged to Contact with the front and rear legs respectively and being ot' equal thickness with the cross connections 6 and which hold the work support from upward movement or tilting when the chair is tilted; an inner end wall and an outer end wall 25 o1 equal thickness with tbe trame member l and arranged to pass thereunder against thelegs l between the 'front and rear trame members 2 and 5. The compartment thus constructed may include a partition 26 extending from 'front to rear and arranged to divide the work materials.

The chair and Work support thus constructed has been applied to use and iound to meet an existing demand.. rlfhe user or oaerator while seated on the chair may move the work support laterally to afford access to the work or contents therein, and the support will be held from tilting when partly withdrawn by the iframe parts 6 and 7. By utilizing the vari-eus parts of the chair to obtain a strengthening struct-ure as described the chair may be subjected to all the strains of indoor or outdoor use over a long period oit time without becoming materially weakened, and without binding the work support. The 1 reven'tion oli' the work support from becoming wedged or bound, and therefore diliicult to operate, is a beneficial result attained by the novel and eliicient structure described resulting from utilizing the cooperative ellect et nearly all of the parts et the chair for this purpose. The construction may be varied within equivalent limits witnout departure from the nature and principle of the invention.

I do not restrict myselit unnecessarily, but what I claim and desire to secure by Letters atent is o A chair comprising two -front and two rear legs, a seat supportedk at the upper end of said legs, a transverse vslat and a transverse guide attached to the rear sides of the front legs below tlie seat and having their lower and upper edges parallel and spaced apart, a transverse slat and a transverse guide at tached to the rear sides ot the rear legs below the seat and having their lower and upper edges parallel and spaced apart, a work support mounted on said guides for sliding movements, front and rear side walls for said support having their upper edges below and adjacent to the lower edges of and in the planes of said slats respectively, an outer end wall attached to said support and having its ends extending beyond said side walls and arranged to extend across portions Voit the outer surfaces ot said legs respectively and having its lower edge extending below said support and constituting a handle, and transverse members attached to the front sides of the front legs and rear sides of the rear legs respectively and having their ends extending laterally beyond said legs and terminating approximately in the plane of the outer surface of said outer end wall.
